MTXPlus+ Design Data - Schematic Files
In due course, i.e., once the relevant board has been
prototyped and tested, this page will host the
KiCad
schematics, other project files, firmware source and object
code.
The CAD files
and custom firmware available on this page have been used to
produce subsystems for MTXPlus+,
a modular
Z80 computer based on the design of the original
Memotech MTX512. The design files available for download have
been used to build the associated modules which has been tested
and confirmed to work as per the design. However, there may be
errors in the material available for download and your results
may differ from mine. If you identify any errors in the design
or firmware and/or make any modifications or enhancements to the
design, please let me have a copy of the information and any
changed or added files.

There is not much available at the moment, but I
have made a start by releasing the
system bus drawing and the
power board in
KiCad
format.
Each of the boards is a separate KiCad project
file and uses one or more custom components that I have either
created myself or downloaded as part of additional KiCad
component libraries. The custom components are either ones that
are not included in the libraries distributed with KiCad,
or have been edited to correct errors or better suit my
schematic layouts. All of the additional components are included
in the Dave2 library file,
this file has evolved as I have made more & more use of
KiCad. As a result, it is a work in progress and should
really be tidied up at some point, until (if) I get round to
cleaning it up, you can either use the library "as-is" or you
may want to extract and/or edit the components for use in your
own libraries.
